Elevation, soil pH and calcium availability shape regional and local scale spatial patterns of PhoD gene abundance in tropical and subtropical forests

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Multiple pregnancy with complete hydatidiform mole and coexisting normal fetus: systematic review and meta‐analysis of clinical outcomes from non‐randomized studies

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 272-282, March 2026.
ABSTRACT Objective Complete hydatidiform mole and coexisting normal fetus (CHMCF) is a rare condition for which there is significant heterogeneity in diagnosis, counseling and management of complications. The objective of this study was to summarize the prevalence of clinical outcomes in reported cases of CHMCF.

Endogenous/Exogenous Dual‐Responsive Bimetallic Hollow Nanozyme for Photothermal/Nanocatalysis/Immune Synergistic Tumor Therapy

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Nanozymes have attracted considerable attention in cancer therapy due to their adjustable enzyme activity and high catalytic efficiency. However, they still face a major challenge from tumor metastasis. In this work, endogenous/exogenous dual‐responsive bimetallic hollow PdRu (termed HPdRu) nanozymes were prepared.

The Role and Mechaninsm study of IL-20-related Cytokines contribute to Autoimmune Myocarditis in Mice [PDF]

open access: yes, 2015
目的:免疫相关因素与心肌炎引起的心肌纤维化密切相关。前期研究表明,IL-10家族成员在心肌炎慢性期心肌纤维化的形成过程中发挥重要作用。IL-20是最新发现的IL-10家族成员之一,具有调节细胞增殖和分化的作用。但IL-20是否参与心肌炎心肌纤维化过程尚不清楚。本课题通过实验探讨IL-20及其相关因子对小鼠自身免疫性心肌炎(EAM)心肌纤维化的影响及可能的分子调节机制。 方法:利用小鼠心肌肌球蛋白多肽MyHC6l4-629和完全弗氏佐剂充分混合后,于第0天和第7天皮下注射建立小鼠EAM模型;组织切片H ...

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem

open access: yesReview of Policy Research, Volume 42, Issue 6, Page 1404-1427, November 2025.
Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant
